Penentuan Kadar Protein, Karbohidrat, dan Lemak pada Serbuk Nano Daun Matoa (Pometia pinnata J.R. Forst & G. Forst)

Abstract

Background: Matoa leaf (Pometia Pinnata J.R. Forst & G. Forst) is one of the plants that contains a large amount of macronutrients. The protein, carbohydrate and fat content in matoa leaves can be used as an alternative in adding nutritional value to processed products. By knowing the protein, carbohydrate and fat content, it can determine the calorific value from a sample. One way that can be done to increase the absorption of active ingredients in a product or formulation is by making nanoparticles. Purpose: To determine the total protein, total carbohydrate, crude fat and caloric values in matoa (Pometia pinnata J.R. Forst & G. Forst) leaf nano powder samples. Method: The steps of this study include sample preparation, sample identification, preparation of simplisia, preparation of nanoparticle powder, characterization of simplisia and nano powder, phytochemical screening of simplisia, determination of nano powder total protein content, determination of nano powder total carbohydrate content, determination of nano powder crude fat content, and determination of nano powder calorific value. Results: Characterization examination of matoa leaf simplisia and nano powder met the requirements of the literature. Phytochemical screening examination of matoa leaf simplisia contains alkaloid compounds, flavonoids, tannins, saponins, glycosides, steroids. The results of determining the total protein content of matoa leaf nano powder was 0.8571%, total carbohydrate content was 0.4617%, and crude fat content was 2.6916% with a caloric value of 294,96 kcal/kg. Conclusion: Matoa leaf nano powder contains total protein content of 0.8571%, total carbohydrate content of 0.4617%, and crude fat content of 2.6916% with a calorific value of 294,96 kkal/kg.
